APPARATUS FORv BINDING PACKING CASES AND SIMI LAR OBJECTS BY MEANS OilHOOPS.

Application filed June 11, 1928, Serial No. 284,564, and in France May14, 1927.

It is the usual practice, .in order to strengthen packing cases or torender them free from the possibility of damage or for contrary, it hasnot hitherto been possible to produce an apparatus which will allow ofcarrying out the various operations necessary. 'lhus such operationsusually are carried out by means of three independent mechunisms; atensioning apparatus by means of which the necessary tension is given tothe hoop, an assembling apparatus which allows of joining the two endsof the hoop, and

shea rs tor-cutting the band of hoop-iron after such assembly has beeneffected.

The present invention relates to an apparatus for stretching a metalhoop and comprises a tightening roll, means for applying one .of theends of the hoop to one of the peripheral points of this roll, means forapplying to the roll at a different point on its periphery, a. part ofthesame band forming the other end of the hoop .to be formed. and meansfor turning the roll about its axis in one direction only, so as toimpart, by this rotational movement of the roll. displacements to thetwo ends of the band in different direetions zmd thus to stretchertighten the same on the articles to be bound. I

The present invention also relates to an apparatus for carrying out allthe operations required in binding, i. e., tightening the band,assembling, with or without clamps, the free end of this band over theother part of the band fedtowards it, and cutting said band. Furtherall'the-se operations are carried out by means of a single operatinglever. As

the attendant does not releasethe-lever during these operations he canconsequently rapidly bind cases and bales of all types.

The accompanying diagrammatic. drawings are given by way of example andare not to be taken as in any way limiting the scope of the presentinvention.

In Figure 1 the binding machine A is shown above a halo at aroundwhichis a metal band I) from a drum 0. The free end (1 of this band isengaged by the'maohine A and the portion 6 also passes through thisapparatus after h: ving passed around the bale a.

By means of the machine A which has just been described, the band passedaround the bale is first tensioned and then the two ends (1 and e arebrought together by means of a clamp f, the band. remaining stretched,and

finally the portion e is cut and separated from the drum 0.

The clamps used for this union of the two ends of thebandconsistofametalplatewhich is preferably previously pierced by a hole9 Figure. 2. The sides k, z of this plate are bent into the form of a U(Figures 3 and 4). A clump of this shape is introduced into the machineA which, when the band is stretched around a bale, forces the sides hand i against the Walls (1 and e of this hoop Figures 5 and 6, widensthe opening 9 of the clamp, perforates the ends (Z and e of the hoop andat the same time seals the ends (1 and 0 together and with the clamp fFigure 6, the sides of the opening g of the clamp being forced into theopenings provided in the ends (1 and e and thus.

preventing any slipping of the end d relative to the end e. As soon asthis has been done, the end e is cut off and separated from'the drum bymeans of the same apparatus.

The binding is then completed and the apparatus A can be withdrawn.

The invention isof course not limited to an apparatus A adapted solelyfor use in combinaiton with clamps of the shape shown in Figures 2 to 6.Clamps of other shapes or type may also be used and the apparatus can beadapted to the shape selected. The apparatus can also be simplified inorder to produce hoops, the two ends of which are to be superimposedwithout a clamp by. any suitable means. Similarly hoops previously cutto the correct length can be used and the cutting mechanism can beeliminated.

The following description refers to a complete apparatus which allows ofcarrying out all the operations described above. This apparatuscomprises a base on which are mounted A tensioning apparatus whichallows of stretching the hoop over the object ,in question as tightly asnecessary,

A mechanism for closing a clamp placed over the tensioned hoop,

A mechanism for binding the ends of the hoop together, 1 i

An apparatus for cutting the hoop, and preferably, a single levercontrolling all such mechanismsp In the example shown in the drawings,the mechanisms are all mounted on'a base 1 pro-'- vided with a handle ,2adapted to facilitate the operation of the machine. r

The single lever 3 is connected with the four mechanisms mentioned, sothat a to and fro motion imparted to the lever through a given anglecauses the functioning ofathe' tensioning apparatus alone, the othermechanisms remaining out of action, whilst dis-. placement of the samelever through asec- 0nd angle forms the clamp,' a.nd displacementthrough a third angle brings the ends of the hoop together and cuts theend of the hoop connected to the feed drum.

Tensiom'ng mechanism.

The tensioning mechanism comprises a roll 4, Figure 12, arranged at oneend of a spindle '5 which carries at the other end a ratchet 6 Iactuated by a pawl 7 mounted on the lever 3. The pawl isheld-permanently against the ratchet '6 by means of a spring 8. .The

. lever 3 rotates "on a sleeve 9 carried by an element 10 mounted onthespindle 5 and provided with a sector 11 acting as' guide for, thelever. i- 1 A pawl 12 bearing against the ratchet 6 under the action ofa spring 13 anchored in the base 1 of the machine prevents any returnmovement of the ratchet 6. p The element '10 is itselfmovable about,spindle-14 mounted on the base 1, Figure 7 position,

The clamp closing mechanism Figures 8, 9

and 10 comprises twolateral levers or jaws 22- .Figure 10 articulated onspindles 23 mounted on the base 1. The lowerportion of each of the jawsis provided with a hook 24 and notch 25. On closing the jaws 22,-thehooks-24 force the two arms hand i of the clamp against thetwe ends dande of the band '6 and these arms thus turned are held inthe twonotches 25in these jaws.v Each of the levers 22 is alsoprovided with an inclinedramp 26 arranged opposite a similarramp 27 on one of the arms 28 of abifurcate member '29, mounted on a sleeve 30 enclosing a spring 31 andlocated opposite .an abutment 32 provided on the base 1. This sleeveisalso provided with an abutment 33' mounted opposite the boss 21 on thelever 3.

Springs 34,}i1iounted between the jaws 22 and. the base 1, keep the jawsopen under normal conditions.

Under these conditions, when a thrust is i b'rought to bear on the boss33-by meansof the levers 3. throughthe boss 21, the ends 27 of.

The stamp 38 is provided with striker-49, arranged above one blade ofthe shears 50 carried by the jaws 22 of the mechanism for closing theclamp, and actuated so as to bite into the end e of the hoop oncompletion of the punching operation so as to leave the end (Z intact.The force of the blow, and the position of the eccentric 48, are to beso regulated that the blade 50 will just shear band end 0 withoutpenetrating into band end at. It is not essential that the shear of bandend 6 be absolutely complete as the fact that portion e of the band isalready under tension tends to tear the band when artially severed.Furthermore, as hereina ter set forth, the swinging away of thetensioning roll tends to pull on band a where it is engaged with thesame, thus to tear band e at the portion where it has beensubstantiallysevered by blade 50, if the tension on the band has not completed theseverance.

The blade 50 of the shears slides in a guide formed in the lever 2 andis held in place by means of the key 51.

This blade 51 cooperates with a shoulder 51' integral with the blade 51acting as an anvil during the cutting of the hoop.

Finally rollers 52, 53 which guide the hoop are inserted in the base ofthe apparatus,

Operation.

The apparatus held by the handle 2 is placedv in the correct posltion onthe article to be bound, for example .a packing case, at the point wherethe binding is to be formed, Figure 1, the actuating lever 3 being leftfree. The jaws 22 are then held open by springs 34. The spring- 45maintains the punch 37 in its raised shears 50 free. I

'The end 0 of the hoop 6 carried by the reel 0 is passed over the roll 4between the latter and the upper boss 17 of the base 1. For this purposethis roll carried by the members 10, 11 isheld away from the base 1 bythe springs 15 until this element just abuts against the base 1, Figure11, at the point 54, and this end e of the hoop is passed below therollers 52 and 53. and then below the jaws 22 (during this adjustmentthe operator bears slightly on the handle 2). The band I) is then woundround the case a and the end is position and leaves the passed below theapparatus under the roll 4, between the latter and the lower boss 18,and then again below the jaws 22 until slightly beyond the same Figure1).

At this moment, t e operating lever 3 is moved in the direction of thearrow in Figurel. The friction of the lever 3 on the element 10, 11wedges the roll between the two ends d and e which then bear against thebosses 17 and 18, so that by giving the lever 3 to and fro movementthrough the angle a. the pawl 7 acts on the ratchet 6, turns the rolland causes the two ends (23 and e to move in opposite directions thustensioning the hoop about the object a. The pawl 12 prevents the ratchetfrom slipping back. As soon as the tension has reached a 'suflicientvalue, the lever 3 is returned to its position of rest and a clamp f,Figures 3and 4, is passed between the jaws 22 up to the cutter 50.

By displacing the lever 3 through the angle 3 toward the handle 2, theboss 21 being then in contact with the boss33, the element 28, 29, 3Oslides between the jaws 22, closes the lat-- ter and consequently forcesthe arms h and i of the clamp against the hoop; then continuing themovement of the lever 3, so as to move it through an angle a, theconnecting rod 42 actuates the levers 40 and 41, and the stem 38 and thepunch 37 are lowered and punch the two ends d and e, uniting the lattertogether and with the clamp f. The hammer 49 then strikes the blade 50which cuts the band to the rear of e only, the band d remaining intact.The sealing pressure is maintained by the lower portions of the levers,and the cutting pressure by the shoulder 51'.

It is to be noted that, shortly before reaching the end of its movement,the lever 3 contact-s with the abutment 16, becomes integral with theelement 11, and its short arm is reduced to the distance 55 separatingthe axis 14 from the boss 33, so that this lever transmits a powerfulblow at the momentof cutting the band. At the same time the roll 4disengages from the band d and the pawl 12, and due to its biting intothe upper band, tends, as it swings away, to carry the upper band withit thereby tearing the band at the portion substantially cut through bythe blade 50, in case the blade has not entirely severed the tensionedupper band, as set forth above.

In order toremove the apparatus it is sufficient, after having pushedthe lever sufficiently back, to'lift the punching end of the device offof the band joint, and then (as the tensioning roll is alreadydisengaged) to push the entire apparatus sideways to slide arm 20 frombeneath the band d.

In the apparatus described above and shown in the accompanying drawings,it has been supposed that a single level-3 actuates all the mechanismscarrying out the various present invention, an apparatus can also beconstructed which allows of carrying out the same operations by means ofa plurality of separate levers, each of which is adapted to carry outone or more of these operations, which levers are actuated successivelyin desired sequence.
